. Application filed June 22, 1918. Serial No. 241,401.

To all whom it may concern:

Be it known that I, Ross B. JoHNsoN, a citizen of the United States, residing at Cherokee,. in the county of Cherokee and State of Iowa, have invented certain new and useful Improvements in Rail-Oiling Machines, of which the following is a specification, reference being had to the accom panying drawings.

This invention relates to machines for spraying liquid, and particularly to machines for applying oil to the bolts and angle bars of railroad rails. v

The general object of the invention is to provide a machine of the character stated designed to travel upon a railroad track and to be driven by any suitable power, the truck of the machine carrying an oil tank and valve controlled spraying nozzles so arranged as to spray oil upon the joints, bolts, and fish plates of railroad tracks.

At the present time, railjoints have to be oiled by hand and the oil or other like mate-. rial is put on with a brush. One man can average one mile of track a day using about five or six gallons of oilv to the mile, and another object of the device is to provide an oiling machine of the character stated whereby the amount of oil may be reduced and the amount of track oiled increased.

A further object is to provide a construction of this character in which oil is forced from the tank under pressure by means of an air pump connected to the tank and driven preferably from the axle of the truck upon which the tank is mounted.

A further object is to provide simple I.

means whereby the oiling pipes may be raisedor lowered and whereby the flow of oil through the pipes may be readily con-' trolled.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of my im-' proved track oiler; I

Fig. 2 is a front elevation thereof; and

Fig. 3 is a detailed sectional view showing the mannerof connecting the piston rod the crank 24. I

Referring to the drawings, 10 designates a truck of any suitable construction, and which maybe driven or caused to travel over the rails in any suitable manner, this truck: being supportedupon-wheels 1i and upon axles 12 resting onthe rails 13. Mounted upon the truck, in any suitable manner, is the oil tank 14. This will referably contain about one hundred ga lons of oil and is provided with the pressure gage 16 and with the check valve 17 having A pump cylinder 18 is operaa .nipple. tively supported upon the frame of the car and from this pump cylinder extends a flexible pipe 19 to the nipple 17 Thus air may be pumped into the tank 14. The pump may be of any suitable construction and is provided with a piston 20 reciprocated by any suitable means connected to the axle 12.

Preferably the piston carries at its outer end a head 21 through which passes the screw-threaded wrist pin 22, the head being held in place upon the wrist pin by nuts 23, this wrist pin passing through a thin metal crank arm 24 mounted upon one of the axles 12. Any other suitable construction for this purpose maybe used, however. One end of the cylinder is hingedly connected to the frame of the truck so that the cylinder may oscillate as the piston reciprocates.

Extending from the tank 14 is a discharge pipe 25 having therein the valve 26 whereby passage through the discharge pipe may be.

controlled, and this discharge lpe extends forward to the forward end of t e truck and is there connected to laterally extending branches 27 having turn cocks 28, whereby passage through the branches may be quickly controlled. Swingingly connected to the ends of the pipes 27 are the downwardly and forwardly extending pipes 29, each terminating at its lower end in a T 30 from whichextends lateral branch pipes 31 which are then formed to extend downward and forward and then inward and are connected to valve nozzles 32 whereby discharge from the nozzles may be controlled.

For the purpose of raising or lowering the downwardly and forwardly extending pipes 29, I provide a lever 33 operating over a rack 34 and operatively connected to, the

pipes 29 by means of the rods 35. By shifting the lever, the oil pipes may be raised or lowered. These levers permit the spray nozzles to be raised or lowered when going over crossings and through switches and does away with the necessity of stopping to raise the pipes. The valves 28 are quickac'ting valves, so as to shut ofi or turnon the supply of oil very quickly and the pet cocks 82 are designed particularly to con- Will be shortened and by setting it toward the rim of wheel, the stroke will be lengthened, thus to regulate the amount of air which is pumped into the tank and to cause the air to replace the oil which is ejected from the spray pipe.

In the practical use of this invention the" tank is filled, but if there should be no'pressure within the tank, then the car isrun backward on the rails for a short distance until about 30 pounds of pressure is secured within the tank. Then the tank is run ahead without using oil to the samedistance and thus the pressure is increased to'60 pounds. Then the valves 26, 28 and 32 are opened and the car is forced ahead. By watching 1 the air gage,the operator can set the pump to keep up the same pressure at all times. A

small pressure relief valve is mountedfin the top of the tank which'willhold the pressure at a certain point but. relieve it if the pres sure is too great. The tank is designed to be pushed by a motor car and run about five miles r "hour. There will be "a man on each s1de of the truck to turn on the oil through'the valves 28 as the sprayer pipes come to a joint. This device will oil every bit of angle bar and bolts and, furthermore, it sprays oil into the-space between the angle bars and the rails and at the ends whereordinarily no oil is applied. This oiling device will oil about five miles of, track an hour, using about four gallons of oil per mile.

While I have illustrated a particular embodiment of my. invention, yet it will be obvious that it may be changed in many ways, without departing from the spirit of the invention, as defined in the appended claims.

Having described my invention, what I' claim is tance greater than the head of a rail and adapted to straddle a rail and having spray nozzles discharging toward the rail straddled by the branches, said branches and noztank mounted thereon, track oiling pipes mounted upon the truck and having branches at their lower ends straddling a rail and having spray nozzles discharging toward the rail straddled by the branches,

and means for compressing 'air Within the tank, the spray nozzles being provided with valves for contrblling the size of the spray discharged and the, oil pipes being provided with valves controlling the volume of oil discharged" fromthe tank. V

i 3. Means for oiling track comprising a truck having wheels adapted to run upon the track, a tank supported upon the truck, a power operated air com-pressing pump con- 'nected to the tank, laterally extending pipes operatively connected to the tank and having quick-operating valves, discharge pipes extending downward from said laterally extending pipes. and disposed over the rails and having branches straddling the rails,

and carrying valve controlled nozzles discharging toward the rails, and means for raising or lowering the discharge pipes.

4. Means for oiling rails comprising a truck having wheels engaging the rails, a

tank mounted thereon, an air pump operatively connected to be driven by the wheels and operatively connected to the pump, a discharge'pipe leading from the tank and havingavalve, laterally disposed pipes having manually operable quick-acting valves and extending to points above .the rails, downwardly extending pipes mounted in advance of the truck and connected to said laterally extending pipes ,and oscillataJble in a vertical plane, each of said downwardly and forwardly extending pipes having lateral branches at the ends embracing the rail and having inwardly extending valved discharge nozzles, and levers operatlvely connected to the forwardly extending pipes whereby they may be raised or lowered.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
